L lfofalli rolzlom aiming/1concern: I H Belt known tliatffI, IvANS.HANSON, a

pitizen of the United States, and a resident of VVinter-IIarbor, in thecounty of Hancock and State ofMain'e, have invented a i new and usefulImprovementin Power-De veloping Apparatus, of which the following 1 Myinventlon relates elastic fluid tur- 10' 'bines machines driventherebyand it .has for'its'obj'eot to provideapparatus v the characterdesignated.- wliich shall have -only' -two bearings for the support ofthe turbine and tlie nac-hine 'roto'rs,'whereby. the 115; structure .maybe' simplified, b l eoononiically built, andhave thebearings easilyvalined.

The generatorshaft 16 is preferably prof with a flange which is securedtothe rotor disk 21. a i p f Froln the foregoing, it will be" apparentthat the turbine and generator rotors are supported by a single pair [ofbearings, namely, the turbine bearing 12' and the gen-' erator bearing15. It will also .be seen that the disk 20 of the high-pressure stage,

at 17 is overhung with respect'to. the intel-mediate turbine bearing'12.v It will,

,.therefore, be apparent, thatI have deviseda turbine and machine driventhereby which is simple, from thestandpoint'of structure and-in which itis assured thatthe generator and turbine shafts shall be maintained in VI alinement, "thereby" avoiding the necessity I for using compensatingcouplings; My ar- 1 rangement also makes it possible to shorten theoverall length 'of a turbine and agen- 'erator of theeharaoterreferredto with'respectto structures of the prior art.

While I have shown my'invention in but one form, it will be obvious tothoseiskilled fications, withoutndepartin'g' from the, spirit thereofand I desire, therefore, that only such limitations shall be placedthereupon the, appended claims; I

WThat Ielaim is:

tioniof a casing, a rotor withinthe casing and having blade-carryingdlsks and a single bearing for therotor arranged be i i tween the disks.r
